Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a conventional ECDIS system is used for ship navigation, then the system structure is simple, but the navigation information is not comprehensive and intuitive enough, leading to potential accidents
Solution Approach 1:
The patent merges multiple information sources including external image data from topographic databases, real-time ship position data from GPS, wave information from radar, and weather data into a single augmented reality display system. This integration provides comprehensive navigation information while maintaining system manageability through unified processing.
Solution Approach 2:
The patent transitions from traditional 2D ECDIS displays to a 3D augmented reality environment where virtual navigation information is overlaid on the real-world view through transparent displays. This dimensional enhancement provides intuitive spatial understanding of ship position, wave conditions, and navigation routes.
2Ease of operation
If a transparent display device is used to show real and virtual environments simultaneously, then the information presentation is improved, but the display structure becomes more complex
Solution Approach 1:
The transparent display device serves multiple functions: displaying external image data from topographic databases, showing real-time ship position and orientation, presenting wave information from radar, and providing weather data. This multi-functionality consolidates multiple display requirements into a single device, reducing overall system complexity.
Solution Approach 2:
The patent uses a camera as an intermediary to capture real-world views and combine them with virtual navigation information. The camera feed serves as the base layer onto which augmented reality elements are overlaid, simplifying the integration of real and virtual environments compared to direct optical combining methods.
3Reliability
If more navigation information is displayed to improve safety, then the stability of ship navigation is improved, but the system requires more complex data processing and integration
Solution Approach 1:
The patent pre-processes and stores external image data from topographic databases in advance, organizing it by geographic location and orientation. This preliminary preparation allows the system to quickly retrieve and display relevant map data without performing complex real-time processing, thereby improving navigation reliability while minimizing processing complexity.
Solution Approach 2:
The system continuously monitors ship position through GPS and orientation through sensors, using this feedback to dynamically adjust which external image data and virtual information is displayed. This feedback mechanism ensures the most relevant navigation information is always presented without requiring processing of all possible data, maintaining reliability while managing complexity.
